how can you add multi database like this? I dont see any example how to config multi database like this, I cant do that

One of the steps during the connection setup asked about selecting a single database, or "show all databases".

If you choose the wrong thing at that step - you can right click the server connection and edit the connection settings. If you leave the "database" value as an empty string, you should get the same effect (may or may not require a reload).
